We've owned our Stealth for a year now and have had no issues. We did have one of the 2x2 supports below the front bedroom replaced because it was splitting. This was done under warranty...no problem.
We don't use our trailer as a toy hauler, we simply like the options you get with a toy hauler floor plan. This being said, we probably don't subject our trailer to some of the wear-and-tear that a toy hauler might see under normal conditions.
